接着上面的博客继续写
3台主机
192.168.1.71
192.168.1.72
192.168.1.73
执行 yum install flannel -y
step1:
在192.168.1.71主机执行
创建一个网络
etcdctl --endpoints=https://192.168.1.71:2379 --ca-file=/etc/kubernetes/ssl/ca.pem --cert-file=/etc/etcd/ssl/etcd-1-71.pem --key-file=/etc/etcd/ssl/etcd-1-71.key mkdir /k8s/network
查看
etcdctl --endpoints=https://192.168.1.71:2379 --ca-file=/etc/kubernetes/ssl/ca.pem --cert-file=/etc/etcd/ssl/etcd-1-71.pem --key-file=/etc/etcd/ssl/etcd-1-71.key ls /k8s
设置网络地址段
下面地址非常大 能使用的ip有 四百一十九万四千多
etcdctl --endpoints=https://192.168.1.71:2379 --ca-file=/etc/kubernetes/ssl/ca.pem --cert-file=/etc/etcd/ssl/etcd-1-71.pem --key-file=/etc/etcd/ssl/etcd-1-71.key set /k8s/network/config ‘{"Network": "10.64.0.0/10","Backend": {"Type": "vxlan"}}‘
step2:
编辑修改flanneld配置文件
192.168.1.71
vi /etc/sysconfig/flanneld
# Flanneld configuration options # etcd url location. Point this to the server where etcd runs FLANNEL_ETCD_ENDPOINTS="https://192.168.1.71:2379,https://192.168.1.72:2379,https://192.168.1.73:2379" # etcd config key. This is the configuration key that flannel queries # For address range assignment FLANNEL_ETCD_PREFIX="/k8s/network" # Any additional options that you want to pass FLANNEL_OPTIONS="-etcd-cafile=/etc/kubernetes/ssl/ca.pem -etcd-certfile=/etc/etcd/ssl/etcd-1-71.pem -etcd-keyfile=//etc/etcd/ssl/etcd-1-71.key"
192.168.1.72
vi /etc/sysconfig/flanneld
# Flanneld configuration options # etcd url location. Point this to the server where etcd runs FLANNEL_ETCD_ENDPOINTS="https://192.168.1.71:2379,https://192.168.1.72:2379,https://192.168.1.73:2379" # etcd config key. This is the configuration key that flannel queries # For address range assignment FLANNEL_ETCD_PREFIX="/k8s/network" # Any additional options that you want to pass FLANNEL_OPTIONS="-etcd-cafile=/etc/kubernetes/ssl/ca.pem -etcd-certfile=/etc/etcd/ssl/etcd-1-72.pem -etcd-keyfile=/etc/etcd/ssl/etcd-1-72.key"
192.168.1.73
vi /etc/sysconfig/flanneld
# Flanneld configuration options # etcd url location. Point this to the server where etcd runs FLANNEL_ETCD_ENDPOINTS="https://192.168.1.71:2379,https://192.168.1.72:2379,https://192.168.1.73:2379" # etcd config key. This is the configuration key that flannel queries # For address range assignment FLANNEL_ETCD_PREFIX="/k8s/network" # Any additional options that you want to pass FLANNEL_OPTIONS="-etcd-cafile=/etc/kubernetes/ssl/ca.pem -etcd-certfile=/etc/etcd/ssl/etcd-1-73.pem -etcd-keyfile=/etc/etcd/ssl/etcd-1-73.key"
step3:
3台 主机启动 flanneld
systemctl start flanneld
设置开机启动
systemctl enable flanneld
查看有没有获取到 10.64网段ip地址
ifconfig
step4:
三台主机都执行
安装 docker-ce 获取 flanneld ip地址段
推荐安装 docker-ce 在实际的使用过程中
下载镜像源 -> 清华大学镜像源
curl https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo
sed -i ‘s#download.docker.com#mirrors.tuna.tsinghua.edu.cn/docker-ce#g‘ /etc/yum.repos.d/docker-ce.repo
yum install -y docker-ce
创建目录修改docker镜像的保存路径
mkdir /data/docker -pv
编辑dockerq启动文件程序
以下操作3台主机都执行
vi /usr/lib/systemd/system/docker.service
[Unit] Description=Docker Application Container Engine Documentation=https://docs.docker.com After=network.target firewalld.service [Service] Type=notify EnvironmentFile=-/run/flannel/docker EnvironmentFile=-/run/docker_opts.env EnvironmentFile=-/run/flannel/subnet.env EnvironmentFile=-/etc/sysconfig/docker EnvironmentFile=-/etc/sysconfig/docker-storage EnvironmentFile=-/etc/sysconfig/docker-network EnvironmentFile=-/run/docker_opts.env ExecStart=/usr/bin/dockerd --data-root /data/docker $DOCKER_OPT_BIP $DOCKER_OPT_IPMASQ $DOCKER_OPT_MTU ExecReload=/bin/kill -s HUP $MAINPID LimitNOFILE=infinity LimitNPROC=infinity LimitCORE=infinity TimeoutStartSec=0 Delegate=yes [Install] WantedBy=multi-user.target
启动docker
systemctl daemon-reload
systemctl start docker
systemctl enable docker
检查docker是否获取到了flanneld网络地址
ifconfig
